Engineering Physics Annotation << Back IMPROVING THE COOLING OIL POWER TRANSFORMERS BY BUBBLING SULFUR HEXAFLUORIDE BUBBLES A.S. KHISMATULLIN, M.R. SURAKOV, A.A. SYNTIMIROV Power transformers industrial facilities need to improve the effi ciency of their use. The paper proposes a method of intensifying the cooling system of transformer oil on the basis of representations about transtsillyatornom heat transfer. The proposed method of intensifi cation of the cooling system by increasing the heat transfer coefficient in the oil can improve the efficiency of the cooling system of power oil transformers. Key words: thermal conductivity, heat transfer, heat transfer transtsillyatorny, sulfur hexafl uoride, a transformer, bubbling, cooling system. Contacts: E-mail: hism5az@mail.ru Pp. 27-31.
